CH'RISTOPHER MOEGLING, OF TvIILWAUKEE, WSGONSIN.

Lezters-Patenf No. 72,317, ama December 17,1867.

MPRVED VENTILATOE POR FLOUR-MILLS.

T0 WHOM IT MAY CONCERN:

Be il: known that I, .CHISTOPHER MOEGLING, of Milwaukee, have invented new a.nd useful Improyemnte in FIour-Mlls; and I do hereby declare the following' to be a. full and exact description of the same, reference being had to.the drznvings thai. accor npany and'form a. part of these specficatons, in wbich- Figure 1 is a. perspectibe view, (vith a. poftion of the curb broker ofl, sbowing the parte attacherl to the running-stone.

Figure 2, sectonal view, with o'utlnes of the educting-ppe on the left.

Figure 3, sectonal.view of the educting-pipc, wth devce for catching the water that may trickle down on the inside of the pipe.

Letter A, the running-stone; letter B,'the curb; letter C, the conveyer or receptacle for the figur; letter D, pipe for carrying ofl the moist-ure; letter E, wings in theside of the stone; letter F, frame to prevent flour from gathering between the running-stone and the curb; lette! g, slots in the face-flange ofthe wings E, for adjusting the ange il: shall have upon the stone; letter k, slots in the frame F, for a.djusting il: vertically lettera, a. stop or preventive to the passing of cold air over the top of the stone t o the flour, and also to the issuing of the heated air, bearng dusf; end mosture into the mill; j, outlt for the flour; k k, shelves in the eductng-piPe D, to stop-the water thai; maycondense in the interior of tbis ppe; l, sbout to ta.ke ofl the water;

0, slide, opening into the spout D; m represents a. device bu1t upon the stone, ci fastened thereto, end rising to the Under side of the top of the curb, shutting ofl the communication wth the space around the periphery of the I,

stdne; n, a-rm of ru bber, leather, or other sutn.ble material, lying across from stona to side ofeurb-a method of losing the space or cutting cfi the communication, tbat may be adopted if -found more convenient, fastened either to the -curb or to the stone.

The object of my inventio n is to provide not only a. cob1ing-device for the flour before it goes to the bolt, but, lso, a device thai: shz1ll evaporate the moisture, end produce a. drying-prcess; this 1atter behg by far the most iuiportant to the manufu.cture of good flour. Indeed, we thix 1k a cooling-process smply is of no practical advnntage whatever, for the cooling only :ordenses the moistu're, wbich is alwa.ys abundant, leaviug it in the 4 flour, making it damp, so it bolts poorly, clogging the bolt-cloth. causing ii: torust and decaj rapidly, while less flour is obtained, as much adheres to the bran.

Now, my plan is te take a.way the moSt air before a.nj cold air can" rea.ch it tocondense the mostpre k I accomplish t his by closng up the spacebetween the top of the ruuning-stone and the ipside of the curb;

This is dome in "arious'waysz by a. band of leather, rubber, or any' other suitable' ma.tria.l, hanging from the under side of the top of the curb andreaching to the top of the runnngstone, es 2', in fig. 1, or the device ma be built up upon the stone, as represented ai: m, in fig. 2; or, if more eonvenient, a. dsl; or other sutable cYosing-dev'ice may be arranged, to lay across from the stone to the curb, as represented byn, in fig; 2.

It is well known thai; as the runn'mg-stone revolves rapidl'y, a. durrent of ar is thrown off from the periphery.

I provide for the passage or escape of the air around the stone, which s warm, an e,rrying much moisture, by ea. ding off a tube or pipe, eibher from some part-of the Club itse1f, or from the receptacle into which the flour fnlls in leaving the stoues.

Halving provided for carrying awa.y the ah that'contains the moisture and other impurtiesx, I can now lei:

in cool air without ma.king the flour damp and clammy. Having shut up the space between the curb end storie, as hereinbefqre set forth, the 0001 air passes down through the eye ofthe upper stone and along the grindng-surfaces of the stonc, preventing hea.ting, causng a. purer grnding than czm possibly be obtained with closing the space over the top of the stone.

In addition to closng the space, as above mentioned, Wngs E may be used, more 01 less in number, on the brphery of the stone. These wingshav'e slots in them, by which the angle they shall have ma.y be regulaterl.

T0 prevent a'.ny flour from remaining between the stones and the c u rb, wbn the wings E are not used, the frame F, or two of t hem, may be used; or, if desired, these ma.y be used as well aswhen the wings are.

T0 prevent any water, that may condense in the interim of the ppe D, fro1p r unning dowrrinto the flout,

Ip1ace the inclinel plates or shelves k k, as in fig. 2501 a circular comfex disk, as represented by k, ir. fig. 3

It is not neessary to use the wings E, nor do I, when usng them, confine myself to any particular form of them.

I am aware that various devces for shutting ofi the ar from going over the top of the stone hmfe. been adopted, but they have been by closing up the usuu1 opening in the top of the curb. This has boen objectionable to In1lcrs, as they have been so long accustomed to look f;o running-stone through this openng, to oberve if it wero running truly, thai: they do not like to have tlxe curb coveredl.

I allow all and even more tha.n the usual openng, ami I do noi: cohfinc myself to any particulur place of forming cut-oif 1'. It may be as reprosented M i, in fig. 1, or by m, in. fig. 2, or by n, as in fig. 2, or in any manner to make a suita.blo stop for the passoge of the air, whilb lea.ving the top of the curb free and open.

If the draught of the pipe D should, for any reason, noi; be sufloient, a fan or any other devioe to increase it, may be used ah its upper end, or at any other suitable place, for eiebting the objoct sought, and ca rry ofF the mosture, without taking away any of the flour.

Wlmt I cla.im as of my invention, and desiro to secure by Letters Patent, is-

1. In connection with an ordinary open4:op curb, the stops 2', m, or n, or their cquivalent, as and for the purposes set forth.

2. I clam 'the educting-pipo D, when provided With the watcr-stops k la, or 7:, whother said pipe leads ofi' from the. curb B, or from the receptaole C, for the prposes speoified, either with or without the uid of the Wings E.

3. I clam the vertioally adjustable frame F, when used as and for the purposes specificd.

In testimony whereof, I have signed my name to this specificaton, in the presence of two subsoribing witnesses.
